MyCalcs is the ultimate TI calculator collection management (and show-off) website!
The collectors list page will give you a peek of who's registered on MyCalcs. There, you can quickly see an overview of their collection (total, distinct, and by-category calculator count).
Your fancy profile page features your name, avatar, community websites links, stats about your collection, and the list of your calculators with all of their info.
You can also export your data!
From your profile page, you can easily add calculators to your collection, thanks to a nice form allowing you to input all of the calculator info at once.
If, at any point, you need to edit your collection, you can do so quickly by modifying values right on the table of your profile page! Just click the edit button above.
